KODAK AEROCOLOR III Negative Film 2444
KODAK AEROCOLOR III Negative Film 2444 is a
medium-speed, very fine-grain color negative aerial film.
This film has a wide exposure latitude and is specifically
designed for processing to a color negative only. Since this
film does not have integral color masking, direct
interpretation can be made from the negative. Objects are
recorded in colors complementary to their natural colors.
The ESTAR Base provides flexibility, moisture
resistance, high tear resistance, and excellent dimensional
stability. KODAK AEROCOLOR III Negative Film 2444
has an abrasion-resistant emulsion, an antihalation
undercoat, and a dyed-gel backing.
The hardened emulsion permits high-temperature, rapid
processing in roller-transport processors, such as the
KODAK Aerial Color Processor, Model 1611, and the
KODAK EKTACHROME RT Processor, Model 1811, with
Quick-Change, using Process AN-6. This process consists of
selected KODAK EA-5 Chemicals and AN-6 Chemicals.
Processing can be easily tailored to optimize contrast for
specific applications.
This film is also compatible with Process C-41. It can be
processed in existing C-41 processors using either KODAK
FLEXICOLOR Developer or KODAK Developer
Replenisher, Process AN-6.
This film can be processed in rewind processing
equipment, such as the Morse M-10 developing outfit
(Military Designator: B-5), although this is not a primary
processing recommendation.
APPLICATIONS
KODAK AEROCOLOR III Negative Film 2444 is for
general use in medium- to high-altitude aerial-mapping and
aerial-reconnaissance photography. It is suited for
geological, pollution, archeological, crop and forestry
studies; traffic control; city planning; railway, highway, and
hydraulic engineering; oceanography; and remote sensing, as
well as other areas where photogrammetry is used. It is also
well suited and recommended for use in digital film
recorders.
BASE
3.9-mil (0.10 mm) ESTAR Base with a gel backing.
TOTAL FILM THICKNESS
The nominal total thickness (unprocessed) of this film is
5.2 mils (0.132 mm). This includes emulsion—0.8 mil
(0.020 mm), base—3.9 mils (0.10 mm), and backing—
0.5 mil (0.013 mm).
WEIGHT
The weight of AEROCOLOR III Negative Film 2444
(unprocessed), conditioned in equilibrium with 50 percent
relative humidity, is 0.04 lbs⁄sq ft (0.018 kg⁄sq ft).
SPECTRAL SENSITIVITY
This multilayer, color negative film is balanced for daylight
exposure.
SAFELIGHT
Total darkness is required.
EXPOSURE
Aerial Film Speeds (EAFS or ISO A equivalent) should not
be confused with conventional film speeds, which are
designed for roll and sheet films used in pictorial
photography. The characteristics of aerial scenes differ
markedly from those of ordinary pictorial or ground scenes
because of the smaller range in subject luminance,
atmospheric haze conditions, and other factors. Therefore,
different film-speed parameters are used to relate
aerial-scene characteristics to practical exposure
recommendations.
The KODAK Aerial Exposure Computer, KODAK
Publication AS-10, has been published based on the aerial
film speed criterion.
Nominal speed, daylight (no filter): EAFS or ISO A 125
(based on development for maximum contrast)
Note: The Aerial Film Speed given in this publication is
rounded to the nearest cube root of 2 step (equivalent to 1⁄3
stop).
Filters
This film incorporates an integral ultraviolet-absorbing filter,
so color correction filters are not normally used. If necessary,
additional color-balance adjustment in the blue region can be
achieved using KODAK Haze Cutting Filters HF-4 or HF-5.
